Application filed May 10,

To all whom z't may concern:

Be it known that I, JOHN J. STARKS, a citizen of the United States, residing at Kansas City, inthe county of Jackson and State of Missouri, have invented certain new and useful Improvements in Staining and Drying Machines; and I do declare the following to be a full, clear, and exact descripothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. v

This invention relates to shingle staining and drying machines, the primary object bein to rovide an improved machine pro? vided wlth a stain reservoir and a receptacle or holder for receiving shingles and submerging them in the liquid in the reservoir to permit them to absorb stain, or the like and to then remove the shingles from the liquid and eliminate excess liquid before the shingles are removed from the machine.

Machines for staining shingles have been used prior to my invention but my invention contemplates an improved form of shingle staining machine so constructed that a comparatively large number of shingles can be stained in a iven time and with'the illustrated embodiment of my invention, a relatively small machine may have a capacity of approximately four hundred bundles per eight hour day.

The novel construction of the invention will be understood by reference to the following description in connection with the v accompanying drawings, inwhich- Fig. 1 is aperspective view of'a shingle staining machine constructed in accordance with 'my invention, and

Fig. 2 is a vertical-longitudinal sectional view through the same.

The illustrated embodiment, of my invention includes a tank or receptacle 1 ofsufii cient capacity and stren h to contain an adequate amount of 'liqui stain indicated at 2. The level of the liquid should be slightly below the top of the tank 1, the upper portion of the tank having an outwardly disare spring pressed .by expansion springs 33 and 34 on springrods 35 and 36, the headed posedcircumferential flange 3 l to support the yoke or frame 4 which rests upon it and which is secured by means of bolts 5 or similar fastening devices.

adapted to be raised and lowered by chains 22 and.- 23 fastened to the pivoted 1924 Serial No. 712,253.

In the bottom of the tank 1 is a step hearing 6 to receive a centrall' located verticalv shaft 7 which is mount notonly in the step bearing 6 but also in the bearings 8 and 9 carried by the yoke frame 4. The bearings 8 and 9 are split bearings to permit the ready'installation and removal of the vertical shaft 7 The vertical shaft 7 carries a mitre gear- 10 driven by a complementary mitre gear 11 on shaft 12 which .may be driven by any suitable means as for example by a belt 13 on pulley 14 carried by the shaft 12,- the belt 1f being driven by any suitable power medium. (eyed or otherwise secured to the shaft 7 1s a propeller form of agitator 15 located adjacent to the bottom of the tank and f adapted to rotate with the shaft to act as a important, however if'the cage is provided v at oppositesides with doors, the introduor tion of the shingles into the cage and the re moval therefrom is facilitated.

At the upper end of the sleeve 16 is a clutch cone 19 which slides with the sleeve on the shaft 7 and which is adapted to enage the cone socket or female member 20 eyed to shaft 7. The cage is adapted to be raised and lowered bya. bridge member or bar 21 provided With'a bearing in which the sleeve 16 rotates. The bridge bar 21 is brake levers 24 and 25, the toes of which are adapted to engagethe pins 26 and 27 of a friction brake disk 28 loosely mounted about the sleeve 16 but carried with the bridge The brake levers 24 and 25 are provided with slots 29'and-30 receiving pins 31 and 32 on the bridge bar and the heels of the levers lower ends of which abut against the abutments 37 and 38 carried by the bridge bar 21. Therefore it will be seen that when the weight of the cage and the bridge bar is carried by the chains 22 and 23, the springs will be compressed, the toes of the lever will be out of contact with the pins 26 and 27 so that the friction disk 28 will be out of contact with the clutch cone 19. Consequently when the clutch cone 19 is moved into the socket 20, the shaft will rotate the sleeve 16 and with it the cage.

In order to effect the raising and lowering of the bridge bar and cage, I have shown the chains 22 and 23 fastened to the sheaves 39 and 40 on the shaft 41 mounted in bearings 42 and 43 carried by the frame 4. The

shaft 41 also carries a relatively large sheave 45 to which'is secured a chain or flexible connection 46 carrying at its lower end a countenpoise or weight 47 to counterbalance the bridge bar shingle receiving cage or holder, therefore little power will be required to elevate or lower the cage.

' In order to elevate or lower the cage, I have shown a sprocket 50 on the shaft 41 around which a chain 51 passes, the opposite end of the chain passing around a sprocket 52 on crank shaft 53 provided with a handle crank 54 so that by turning the shaft 53 in either of two directions, the cage can be raised or lowered and in order to hold the cage in any elevated position, I provide a ratchet wheel 55 on shaft 53 to be engaged by a dog 56, see Fig. 1. A chain ti htener 57 ma be employed if desired.

Iounted on t e receptacle 1 is a counterpoised foot or pedal lever 58 having a rod connection 59 with a bell crank lever 60 mounted on shaft 61, the shaft 61 carrying a detent or dog 62- to engage under the end of the bridge bar 21. A similar dog 63 is pivoted at 64 to the frame and it is provided with a crank 65 connected to a reverse motion lever 66 pivoted to the frame at 67, the connection being efi'ected through a link rod 68, the reverse motion lever 66 being connected to the bell crank 60 through a link 69.

Carried by the top of the receptacle 1 and by the frame 4 is a circumferential wall 70 provided with an opening 71 adapted to be closed by a sliding door or gate 72 but having slidmg movement so that access can be had to the cage to introduce or remove shingles therefrom.

When the parts are assembled the operator can turn the crank 54 to raise the bar 21 and with it the shingle carrier or cage. The cage and bar can be raised until the endsof the bar 21 are in position to be supported by, the hook shaped detents 62 and 63 whereupon the ends of the bar 21 Wlll ride over the hooked ends of the detent 62 and 63 and rest upon the hooked ends.

If the door 72 is opened and the doors 18 of the cage are opened, an appropriate number of shingles can be introduced into the cage, then the doors 18 will be closed, the door 72 closed and the operator will press upon the pedal 58 to cause the detents 62 and 63 to move from bridge bar engaging Eosition to bridge bar releasing position.

y turning the crank 54 in a clockwise direction, the chains 22 and 23 will unwind from the sheaves 39 and 40 to allow the bridge bars to move downwardly to a position to submerge the cage or shingle holder, the shaft 7 turning this time, ma be rotated without rotating the cage. en the cage reaches the lower position shown in Fig. 2, the stain will enter through the wire mesh of the screen-like walls and be absorbed by the shingles. All the while the stain will be agitated by the stirrer or agitator 15, then the operator. can turn the crank in a clockwise direction to cause the shaft 41 to turn the sheaves 39 and 40 to wind the cables or chains 22 and 23 raising the bridge bar until the clutch cone 19 comes into contact with the rapidly revolving socket 20 on shaft 7. When the clutch cone 19 engages the clutch socket 20, the cage will partake of the rotative movement of the constantly rotating shaft 7 and will rotate with it at a rapid rate to throw off by centrifugal force any excess liquid, the excess liquid being thrown against the wall 70 surrounding the space above the liquid and thereby forming a drying chamber.

While the cone 19 is in engagement with the clutch socket .20, the ends of the bar 21 will be supported by the detent members 62 and 63. After the shaft has rotated the cage a sufiicient length of time, the operator may slack up chains 22 and 23 by a reverse turn on crank 54 so that the springs 33 and 34 can force the toes of the levers 24 and 25 against the pins 26 and 27 to cause the brake 28 to engage the recessed portion of the cone 19 and since the collar 28 has an up and down movement but no rotative movement, it will be apparent that the cage will suddenly come to rest so that access thereto may be had. The shingles may now be removed in a relatively dry state devoid of excess moisture because this has been closed by the wall 70. A new batch of shingles will now be introduced into the cage and the cage can be submerged and be subjected to the violently agitated li uid in the tank which has been described a ve until a suiiicient length of time has elapsed, whereupon the cage will again be raised and the cycle of operations above described will be repeated.

While I have described the device as particularly applicable for use in staining shingles, I do not wish to be limited to the device as a shingle staining machine for obviously the invention would operate in identically the same manner as described irrespective of the contents of the cage.

What I claim and desire to secure by Letters-Patent is:

1.
